This invention relates to the protectionof open casement windows from the effects of rain, sleet, snow and the like.

p In casement windows as. now constructed; space is left across the top and bottom-as well as down along the sides of the window whenever the window is opened and so far as known, no practical means have been de- 7 vised'thus far to prevent the entry of rain m and snow and the like, even when the win dow is swung open to only a small extent. Casement windows are usually set ,at the outside of the wall, with a deep window-sill extending out to'theframe of the window. 3 Rain and snow enteringthrough a partially opened window therefore will usually fall and :collect directly on the window sill, in many cases spoiling the finish of thesame and running from there down on to ad] acent 2 furniture or the wall covering. It is therefore usually considered necessary and has become customary to entirely close casement windows, when rain or snow storms arise, contrary to desires as to ventilation, etc.

he objects of this invention are to provide a frame construction suited to casement window structures and which can be quickly taken down or be set up to exclude rain; and

or circulation of air.

These and other objects of a like nature are attained in the invention herein-disclosed and by the novel features of construction, combinations and relations of parts hereinafter described and broadly claimed.

The drawings accompanying and forming part of the following specification illustrate certain practical commercial formsthe invention may take; but it should be understood that the structure may be modified and changed as regards the present disclo sure, all within the true intent and broad scope of the invention.

Figs. 12 and 13 are broken sectional de-. tails as on lines 1212 and 13-13, respectively, of Fig. 11, Fig.;13 illustrating by dotted lines the toggle action by which the protector frame is retained in the expanded position interlocked with the flanges of the window frame.

In the several views, casement windows 15- of more or less standard or conventional design are shown mounted in the window frames 16. These frames as indicated in- Fig. 2 are usually set in the outside face of the-wall structure 17 providing deep win-V dowsills 18 extending out practically to the weather-line of the building.

It is typical of these casement window frames that they have narrow inwardly extending flanges 19 defining the window opening and designed to be engaged at the outside by the sash frame of the swinging winadapted to exclude heavy moisture, such as rain and the like. This material preferably is water-proofed without closing the pores so that it will withstand continued weathering. Water-proofed porous muslin and the like may be used for the purpose.

This porous weather-proof screen is supported and held in stretched or expanded shape over the window opening by'a suitable collapsible frame engaged with the inwardly extending flanges of the easement window frame. In the first form of the invention illustrated, this knock-down frame is made up of side bars 21, 22 grooved at 23 to fit over the side flanges 19 of the window frame and connected top and bottom with cross bars 24 hinged intermediate their length at 25. For bracing purposes, an intermediate cross bar at 26 is indicated and the three .cross bars are shown as connected together .tector frame to the window flanges.

at one side of the center of the frame by an upright 27 and at the opposite side of the center by an upright bar 28, which serves the additional function of locking the pro- For the latter purpose, the upright 28 is indicated as forked at its lower end at 29 to engage over the bottom flange and as forked at its upper end at 30 to engage over the top flange. The top fork 30 is shown as grooved 'more deeply than the lower fork so as to permit bar-28 to be lifted to clear it of the,

bottom flange, after which said bar may be dropped sufficiently to clear the grooved upper end of the same of the top flange. To permit the required up and down movements necessary in engaging the bar 28 with and disengaging it from the window frame flanges. without distorting the collapsible protector frame, said bar is shown slotted at 31 where it is held by the headed studs 32 to the three cross bars. Also a handle 33 is shown provided on this movable locking bar to facilitate the necessary movement of such bar and provide a convenient grip for the handling of the frame in placing it in or removing it from the window opening.

The fabric or protective material is suitably attached to the sections of the frame,

as by the ties or connections 34 and the binding strips 35, the latter being shown in Fig. 3 as attached along the side bars 21,22 as by rivets or other suitable fastenings 36.

This same view illustrates how the outer side of the grooved side strips may be elongated at 37 to overlap the windowframe flanges to fully interlock the side bars over the side flanges, bar 28 being then lifted to first engage the forked upper end of the same over the top flange and then lowered slightly to engage it over the bottom flange of the frame. In this condition, the frame is held expanded, with the fabric stretched tight and smooth and is locked to the casement flanges so that it cannot shake loose or fall out. At the bottom the fabric may be permitted to hang from the lower cross bar as a somewhat loose skirt as indicated at 38, Fig. 1 so as to fall down in water-shedding relation over the outside of the bottom flange and drape itself closely over the window holding bar or regulator 39. p

The protector'may be as easily removed by simply grasping thehandle 33, lifting the slide bar 28 to clear the lower casement flange and then drawing it inward and dropping it slightly to clear the upper casement flange, after which a further inward pull will partially collapse the frame and withdrawthe entire structure from the window opening.

The form of the invention illustrated in Figs. 5 and 6 differs from the first form principally in that the frame structure is made up simply of a number of cross bars or slats 40, caught to the fabric as by stitching or the like, in spaced relation and having forked ends 41, similar to the grooves of the side bars so as to engage and interlockov'er the side flanges of the casement frame. These slats or cross bars may be sufiiciently flexible so that they can be bent or deformed enough to snap them over the flanges, or. they may be engaged with the flanges one after another by tipping or inclining them as indicated in the broken lines, Fig. 5. At the top, spring hooks 42 are shown connected with the upper cross bar and removably engaged over a suitable support, such as the ledge 43-which is usually present at the inside over the top of the window opening.

As shown in Fig. 6, the fabric may be extended about the edges beyond the frame structure as at 44, so as to fully overlap over the outside of the casement-flanges.

The second form of the invention just considered, has the advantage that when removed it may be quickly rolled into a small compact bundle. The cross slats may be held by insertin them in pockets 45 stitched across the width of the material, as indicated in Figs. 5 and 6 and the fabric may be suitably caught to the ends of the slats, as by prongs struck out from the slats, if the latter are of metal, or by rivets or other fastenings, such as those indicated at 36 for securing the binding tape or edge strip material 35 in place.

In Figs. 7 and 8, a simplified form of expansible frame is shown in which the grooved side members 21, 22 are simply connected by the intervening fabric and are held in the expanded relation and engaged with the side rails of the casement frame by spreader bars 46, each hinged at one end at 47 to one of the side bars and adapted to engage at its free end in one of a series of saw-tooth notches 48 in the other side bar.

A variation of the last form of the invention is illustrated in Figs. 9 and 10, involving the provision of an intermediate upright 49 attached to the fabric as at 34 and caught over the upper and lower casement flanges after the manner of the slide bar 28 in Fig. 1, the hinged spreaders in this case being broken in two parts 46a pivoted to the opposite side bars and cooperating at the center with the teeth of the oppositely facing ratchets 48a on the opposite sides of the center upright.

The form of the invention illustrated in Figs. 11, 12 and 13 is generally similar to that shown in Fig. 1, having a central slide bar 2801, but differing principally from the first form in having this slide bar made with intermediate toggle sections 50 hingedly connected together at 51 and hingedly connected at their ends at 52 with adjoining portions of the slide bar. This toggle structure, it will be observed in Fig. 13, may be utilized by straight push and pull movements of the handle 33 to extend the forked ends of the slide bar sections over the top and bottom flanges .or to withdraw them from such engagement. In the projected relation, the center hinge of the toggle may be permitted to swing outward beyond the dead center, as shown in the broken lines, Fig. 13 so as to thereby lock the toggle and hold the bar securely engaged at its ends with the casement flanges. This construction has the advantage that the protector may be unlocked and drawn out of the window frame by a straight pull on the handle and may be placed in the frame by simply engaging the side bars over the side flanges and then pushing on the handle to extend the side bar sections into interlocked engagement over the top and bottom casement flanges. V r

In all forms of the invention, the protector may be readily and easily applied to the casement flanges as soon as the window mitted to circulate freely so that there is no practical loss of ventilation in the use of the device. The protector is as quickly and easily removed at any time and the ready collapsibility of the same enables it to be conveniently stored in small space.

The screen material may be a fairly wide mesh fabric, so as to freely pass ventilating air and the water-proofing of such fabric without closing the pores, not only preserves the fabric but causes the rain to run off and prevents the fabric from soaking up molsture and consequent loss of porosity. The window, swinging open in horizontal fashion provides wedge-shaped openings at top and bottom and, at the wide open side, a convergent pocket into which the wind will naturally drive any rain or the like. By" locating the screen on the easement flanges and in position overlapping the outer faces of said flanges, it is positioned substantially in the same plane that the window occupies when it is closed and so has sub stantially the same rain-shedding effect and at the same time takes up no useful space at the inside of the casement frame. The bracing of the screen material at intermediate points prevents the material from sagging and bulging even under the attack of heavy rain with wind.

What is claimed is:

A frame for a rain-excluding ventilating fabric screen for casement windows or other wall openings having flanges extending inwardly of the same, comprising a collapsible frame consisting of members notched to fit over said above mentioned flanges and adapted to be connected with the edge portions of the ventilating rainexcluding fabric at points to hold the same fully stretched continuously across the space outlined by the flanges when said notched parts of said members are engaged over' said flanges and releasable means for removably retaining said members spread apart in position thus engaged over the flanges and supporting said fabric in position closing the opening against rain'but passing air for ventilation.

In testimony whereof I aifix my signature.
